My present invention relates-130*- improvements in'saatransmission and a'ppertains particularly to a.novel direction-changingv shaft, coupling;

An object of the invention is to provide a mechanism for varying the direction of a revolvin shaft.

An object is to provide a shaft coupling consisting of engaging gear shafts and sleeves revolvably enclosed in a suitable housing.

The device includes in combination with a pair of non-aligned spaced revolving shafts, either of which may be driven from a suitable source, a direction-changing means consisting of gears and shaft coupling.

To the accomplishment of the above and related objects, the invention resides in the construction, combination and arrangement of parts as shall be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

The invention will be best understood and can be more clearly described when reference is had to the drawings forming a \part of this disclosure wherein like characters indicate like parts throughout the several views.

In the drawings:

Figure 1 is an elevation of a mechanical structure employing my transmission mechanism, parts thereof being broken away;

Figure 2 is an enlarged detail of a portion of the instant type of novel shaft coupling employed.

This transmission is shown applied to a mechanical structure comprising a fixed compound annular gear or gear ring I mounted on a standam 2 from which it is laterally offset. The gear i has an exterior gear trough la and an interior gear trough lb of the same radius. An hypocyclical gear pinion 3 runs in the interior trough I 2;- a lent-bf this: application. and; connects: the hubs of? the twongearsa 3; andz l4: comprises a substantially semicimularrseetion. oftubular housing l5- whose opposite open ends are suitably journalled on or connected with the hubs of the gears 3 and M respectively, which due to the particular structure shown retain a constant spacing. Between these gear pinions, and supported within the housing l5 are a series of shafts l6 with gears H on each end and connecting sleeves I8 interior- 1y geared at both ends to engage with said pinions H, as may be seen in detail in Figure 2.

The gears l1 are here shown as double bevels and are engaged between a pair of confronting bevel gear rings l9 interiorly mounted near the respective ends of the leeves l 8. Either b longitudinal adjustment of the gear rings [9 in the sleeve l8 and/or the longitudinal adjustment of the double bevel pinion l'! on the shaft Hi all slack, in this type of shaft coupling can be taken shaftoupling to the second gear pinion l i.

lb and is mounted for rotation on the cranked end 4 of a shaft 5 that extends axially through the compound gear ring I whose hub 6 is offset to the supporting standard 2. The far end of the shaft 5, beyond the standard, has a pulley 1 adapted to be driven by any suitable means.

Mounted to rotate on the gear rings offset hub t is a large disk or gear 8 and a pulley 9 applied laterally thereto. The former with a pinion ill on a shaft l l passing through the standard '2 near the bottom thereof and carries a pulley l2 on its other end off which power may be taken. Near its circumference this large disk or gear 8; carries a stub shaft [3 that serves as an axle spindle for rotatably supporting an epicyclical gear l ilthat runs in the exterior trough la.

' The specific shaft coupling which is the ub- From the foregoing description taken in connection with the accompanying drawings, it will above description and many apparently widely different embodiments of the invention may be constructed within the scope of the appended claims, without departing from the spirit or scope thereof,' it is intended that all matters contained in the said accompanying specification and drawings shall be interpreted as illustrative and not in a limitative or restrictive sense.

Having thus described my invention, what I claimi as new and desire to secure by Letters Patent is:

1." AI transmission mechanism having means for chan ing direction, consisting of a train of rotatdisposed at an angle thereto, and being interiorly geared at both ends to engage said shaft gears, and means for rotatably supporting both said shafts and said sleeves.

2. A transmission mechanism having means for changing direction, consisting of a train of rotating parts and comprising angularly disposed, longitudinally spaced shafts, frictiongears on the ends thereof, sleeves between said shafts, and at an angle thereto, confronting spaced friction gear rings interiorly mounted in the ends of said sleeves to engage with said first mentioned friction gears, and means for rotatably supporting both said shafts and said sleeves following the contour of the change of direction of the trainmg parts and comprising angularly disposed, longitudinally spaced shafts, friction gears longitudinally adjustable on the ends thereof, sleeves between said shafts, and at an angle thereto confronting adjustably spaced friction gear rings 4 interiorly mounted in the ends of said sleeves to mesh with said first mentioned friction gears, and a housing formed of laterally separable half shells, for rotatably supporting both said shafts and said sleeves, following the contour of the change of direction of the train of rotating parts.
